WAD FOE SHOT SHELLS.

Application filed April 24, 1822. Serial No. 556,185.

T 0 all whom it may concern:

Be it known that we, HENRY W. GREGORY and GEORGE F. Burrs, citizens of the United States residing at Norwalk, county of Fairfield, State of Connecticut, have invented an Improvement in lVads for Shot Shells, of which the following is a specification.

This invention relates to wads for shells, cartridges and guns, and especially to wads for paper shells, although it is by no means confined to use therewith.

It is an object of the invention to provide a wad which will be waterproof and thus render the shell or cartridge waterproof, which will greatly increase the efiiciency of the powder and improve the ballistic effect.

With these and other objects in view we have devised the wad illustrated in the accompanying drawing in which Fig. 1 is a side view of a shell with a portion cut away to show wads in position.

Fig. 2 is a plan view of a wad involving our invention.

Fig. 3 is a side view of the preferred form and Fig. 4 is a side view of a slight modification.

In forming the wad a sheet of material having the desired stiffness such as hair felt, and the like is covered on one or both sides with a layer of rubber from which the wads are out. Although various materials may be employed, we prefer to make the body of hair felt and cover the same on one or both sides with the layer of rubber. As shown by the experiments so far conducted this appears to give the better results. Also it is preferred to put a layer of rubber on both sides of the body of the wad, but a layer of rubber on one side only of this body gives very satisfactory results. The wad of course is cut so as to fit tightly the interior of the shell, and as the layer of rubber fits tightly this interior wall it forms a very tight joint which prevents entrance of moisture and greatly reduces the leakage of gas when the power charge is fired, thus increasing the efliciency of the powder and improving the ballistic effects.

In the drawings 5 represents any suitable shell as for instance a shot gun shell showing our preferred form of wad in position therein between the charges of powder 6 and shot 7 In our preferred form of wad the body 8 is composed of hain felt to the two sides of which is applied a layer of rubber 9, the layers of rubber being securely fastened to the felt. This construction renders the wad waterproof thus rendering the shell waterproof and thorougly protecting the powder charge. When the shell is fired the layers of felt and rubber form a tight oint with the walls of the shell preventing the leakage of gas thereby and greatly improving the ballistic effects. Very good results may however be obtained by placing a layer of rubber on one side only of the body of the wad as shown in Fig. 4.

Having thus set forth the nature of our invention what we claim is:

1. As a new article of manufacture, a wad for shells or guns comprising a body member composed of suitable material to give it the required stiffness, and said body being covered on one side with a layer of rubber. v

2. As a new article of manufacture, a wad for shells or guns comprising a body of hair felt covered on one side with a layer of rubber.

3. As a new article of manufacture, a wad for shells or guns comprising a body member composed of suitable material to give it the required stiffness, and said body being covered on both sides with a layer of rubber.

4:. As a new article of manufacture, a wad for shells or guns comprising a body of hair felt covered on both sides with a layer of rubber.

5. As a new article of manufacture, a wad for shells or guns comprising a body of felt covered on one side with a layer of rubber.

6. As a new article of manufacture, a wad for shells or guns comprising a body of felt covered on both sides with a layer of rubber.

In testimony whereof we affix our signatures.

HENRY W. GREGORY. GEORGE F. BETTS.
